how can we do sorting in Map in Java ??

Answer 1

Additionally to Boem Shakalaka 's answer you could:
1. Use a sorted map/tree map
2. Stream the map and sort it by using a comparator (if you want to define your own order and not the natural order that is implemented in the api)
Note that a hashmap is defined as unordered.
